Abstract:
A vehicle route guidance system considers driver preferences, vehicle parameters such as speed and performance capabilities in a navigation computer, and outputs flexible guidance instructions based on these considerations. The system monitors vehicle parameters such as current location and speed with sensors such as an odometer (109), a compass (115), and a GPS receiver (113). The system also determines the location of a vehicle manoeuvre and then, considering the former attributes with a model free mechanism, in this case a navigation computer with fuzzy inferencing (101), communicates to the driver instructing him how to manoeuvre.
Abstract:
A vehicle route planning system takes a trip origin location and a trip destination location provided by the driver then considers alternative routes, taken from a map (107), between the trip origin location and trip destination location. Certain attributes, such as traffic congestion and concentration intensity, and driver preferences are considered in a fuzzy inferencing device for planning a preferred route.

Abstract:
Un système de guidage indiquant à un véhicule l'itinéraire à suivre utilise un ordinateur de navigation pour prendre en considération les préférences du conducteurs et les paramètres se rapportant au véhicule, tels que la vitesse et les caractéristiques de fonctionnement, et produit des instructions de guidage flexibles en fonction de ces considérations. Le système surveille des paramètres se rapportant au véhicule, tels que l'emplacement et la vitesse acutels, à l'aide de capteurs tels qu'un compteur kilométrique (109), un compas (115), ainsi qu'un récepteur GPS (115). Le système détermine également les endroits où une manoeuvre particulière du véhicule sera requise, et, en analysant les attributs précédents à l'aide d'un dispositif dépourvu de modèle, dans le cas présent, d'un ordinateur de navigation à inférence floue (101), communique au conducteur des instructions relatives à la manoeuvre.
Abstract:
A vehicle (100) includes vehicle systems (11-13) coupled to a vehicle bus (10) and user devices (40-60) coupled to a user bus (30), the user bus coupled to the vehicle bus by a gateway (20). The user bus transports user information and the vehicle bus transports vehicle information. Based on one or more gateway rules, the gateway transports vehicle information to the user bus for the benefit of target user devices. Also based on these gateway rules, the gateway transports user information to the vehicle bus for the benefit of target vehicle systems. The gateway rules are programmed by both user devices and vehicle systems as follows: First, a proposed rule is provided (303) to the gateway. Second, the gateway determines (305) when to accept the proposed rule based on a variety of factors. Third, when the proposed rule is accepted, the proposed rule becomes (307) a gateway rule.
Abstract:
Systems and methods are provided for controlling use of uplink random access channels (RACHs) based on multi-dimensional subscriber classification. These systems and methods are useful in cellular communication networks that implement, for example, a public safety cellular system.
Abstract:
A method of route guidance for a vehicle with off-route detection includes determining a previous maneuver location and a next maneuver location of the vehicle, then waiting until a distance traversed by the vehicle is greater than a first portion of a distance between the previous maneuver location and the next maneuver location (113). Then, providing a route guidance instruction (111) if a heading of the vehicle indicates traversal towards the next maneuver location. Also, an off-route indication can be provided (119) if a heading of the vehicle indicates traversal away from the next maneuver location.
Abstract:
A multi-mode route guidance system and a corresponding method for same include a device to determine a present position, and an input device (111) for inputting a destination position. A map database (115) provides memory capable of storing a first type of record (225) that has topology and connectivity information (227), and a second type of record (217) that has topology, connectivity, and traffic flow restriction information (227, 229). A route guidance device (101) retrieves selected records (217, 219, 221, 223, 225) from the map database (115), determined by the specified destination position and the present position of a traveler. The route guidance device (101) uses a selected record of the first type (225) to provide ground track guidance cues (601) to the traveler, and a selected record of the second type (217) to provide maneuver instruction guidance cues (501) to the traveler.
Abstract:
An improved accuracy sensory system for vehicle navigation employs a sensor, such as a compass (515), or an odometer (509), for sensing a navigation parameter of a vehicle. A signal is provided from the sensor (509), having an erroneous component. A model free recognizer, such as a fuzzy inferencing navigation computer (501), is employed to recognize this erroneous behavior. After recognition, the sensor can be recalibrated, or assigned a clearness coefficient. The signal is then combined with other measurements of the same parameter and subjected to map matching before deriving the final navigation variable.
